When there is an issue in selecting Purchase Order Document number on inbound shipments, you can try the following
- Edit the Purchase Order which is missing on inbound record
- Close the item lines that are not available on Inbound Shipments using the Closed column on the item line. Close all the item lines if Po has more than one item line.
- Click Save.
- Edit the same Purchase Order again.
- Reopen all the item lines and hit save again
- This purchase order will be available to select on inbound shipments now.
Tip: If there are so many purchase orders to close and reopen item lines / one purchase order has many item lines to close and reopen then it will be difficult to do the same manually. So you can do this in bulk using import. Create a saved search for the purchase orders with item line ID in results. Using purchase order internal ID and Item Line ID, update the POs to close the item lines(Closed field map to yes) and with the same saved import reopen the item lines(this time map “Closed” field to “No”).
